Description

  The present invention relates to an airbag device including a cushion that inflates and deploys to protect an occupant when an impact occurs in a vehicle due to a collision accident or the like.

  When the vehicle collides from the side (hereinafter referred to as “side collision”) or from the front (hereinafter referred to as “normal collision”), the occupant is in a collision direction relative to the vehicle due to inertia. Try to move (side or front). In order to suppress such movement of the occupant in the collision direction, an air bag is provided at the center of the steering wheel in the case of the driver's seat and at the front of the vehicle such as the upper portion of the instrument panel in the case of the passenger seat. It is attached. Furthermore, in order to ensure that the movement of the occupant in the side collision direction is reliably suppressed, a curtain airbag device is installed on the side of the vehicle, and a side airbag is installed inside the seat.

  From the viewpoint of the occupant, there are two types of side collisions: a collision on the near side (near side) and a collision on the far side (far side). For example, in the case of a far-side collision, the occupant may move greatly toward the center in the vehicle width direction (far side) due to inertia at the time of the far-side collision, and may collide with an occupant in the adjacent seat or a hard interior part in the vehicle interior. .

  Assuming such a situation, for example, as disclosed in Patent Documents 1 to 4, between two seats arranged side by side in the vehicle width direction of the passenger compartment, represented by a driver seat and a passenger seat A far-side airbag device (vehicle occupant protection device) is being developed. The far-side airbag device inflates and deploys a cushion upward from a center console between the driver's seat and the passenger seat, thereby protecting a passenger who has moved to the far side.

  However, depending on the state of the collision, the occupant may move toward (obliquely forward) between the airbag attached to the front portion of the vehicle and the curtain airbag attached to the side portion of the vehicle. In this case, since there is nothing that restrains the occupant, the occupant may slip through between the airbag attached to the front portion of the vehicle and the curtain airbag attached to the side portion of the vehicle. As a result, there is a concern that the occupant may collide with interior parts in the vehicle.

  Some vehicle models do not have a center console. In such a vehicle type, the passenger compartment floor between the driver's seat and the passenger seat is often a passage through which passengers can walk. However, since the center console does not exist, the far-side airbag device cannot be provided, and the occupant's waist cannot be restrained by the center console. As a result, there has been a problem that the amount of movement of the occupant's waist to the far side during a collision is greater than in a vehicle having a center console. Even in this case, there is a concern that the occupant may collide with an interior part in the vehicle, or may collide with an occupant in the adjacent seat.

  In view of such a problem, an object of the present invention is to provide an airbag device capable of protecting an occupant by restraining the occupant from moving obliquely forward and moving to a far side at the time of a collision. .

  In order to solve the above-described problems, a representative configuration of an airbag device according to the present invention includes at least a waist portion of an occupant seated on a seat provided on a floor of a passenger compartment or embedded in the floor and inflated and deployed. It includes a cushion that reaches an equal height.

  According to such a configuration, since the cushion is provided on the floor of the passenger compartment or embedded in the floor, the two seats arranged side by side in the vehicle width direction of the passenger compartment or the diagonally forward side of the outer side of the seat. A cushion can be disposed between them. In other words, according to the present invention, a part of the cushion of the airbag may protrude on the floor, but most or all of the cushion of the airbag is embedded under the floor. As a result, the space between the airbag attached to the front portion of the vehicle and the curtain airbag attached to the side portion of the vehicle can be filled with the cushion at the time of collision. It is also possible to fill a space on the passage that exists between two seats arranged side by side in the vehicle width direction of the passenger compartment with a cushion at the time of a collision. As a result, it is possible to protect the occupant by restraining the occupant from moving diagonally forward or moving to the far side during a collision.

  The airbag device may be a far-side airbag device that is deployed between two seats arranged side by side in the vehicle width direction of the passenger compartment. With this configuration, the space on the passage that exists between the two seats arranged side by side in the vehicle width direction of the passenger compartment can be filled with a cushion at the time of collision, so that the movement to the far side at the time of collision It is possible to protect the occupant by restraining the vehicle.

  In particular, when the cushion is inflated and deployed, it reaches the height equal to at least the waist of the occupant seated on one of the two seats from the floor or floor of the passenger compartment. , Restrain the occupant's waist. Therefore, it is possible to suppress the amount of movement of the occupant's waist in the vehicle width direction and prevent the occupant from colliding with an occupant in the adjacent seat or an interior part.

  Further, since the airbag device of the present invention is provided on the floor of the passenger compartment or embedded in the floor, it can be provided not only between the driver seat and the passenger seat but also between the rear seats. Therefore, it is possible to suppress the amount of movement of the lumbar part of the occupant of the rear seat in the vehicle width direction, and it is possible to further improve safety.

  The cushion reaches a height equal to the head of an occupant seated on one of the two seats, and is formed above the first chamber to restrain the occupant's waist, and the occupant's head And a second chamber to be constrained. According to such a configuration, it is possible to restrain the occupant's head also by the second chamber. Therefore, it is possible to more reliably prevent the occupant from colliding with the occupant in the adjacent seat and the interior parts.

  The cushion may be inflated and deployed so as to be sandwiched between two seat cushions. By doing in this way, it is possible to inflate and deploy the cushion more stably.

  The airbag device includes a first cushion that is provided on a floor of a passenger compartment or embedded in the floor and reaches a height equal to at least a waist of an occupant seated on one of the two seats when inflated and deployed. A second one which is provided on the floor of the passenger compartment so as to be lined up next to the cushion in the vehicle width direction or embedded in the floor and reaches a height equal to at least the waist of an occupant seated on the other of the two seats when inflated and deployed. It is good to include a cushion.

  According to this configuration, it is possible to fill the space on the passage existing between two seats arranged side by side in the vehicle width direction of the passenger compartment with the two cushions at the time of a collision. In particular, one cushion that restrains the waist of one occupant is supported on the other side by the other cushion, so the amount of movement is reduced compared to the case of using a single cushion, and the occupant falls too far into the far side. It is prevented.

  At least one of the first cushion and the second cushion includes a first chamber that restrains the occupant's waist and a second chamber that is formed above the first chamber and restrains the occupant's head, and includes two seats It is good to have the height which reaches | attains to the height equal to the passenger | crew's head seated on at least one. According to such a configuration, it is possible to restrain the occupant's head also by the second chamber. Therefore, it is possible to further prevent the occupant from colliding with another occupant or another object.

  The first cushion and the second cushion may be inflated and deployed so as to be sandwiched between two seat cushions. By doing in this way, it is possible to expand and deploy the first cushion and the second cushion more stably.

  The airbag device is an airbag device that is deployed obliquely forward on the vehicle exterior side of a seat that is arranged side by side in the vehicle width direction of the passenger compartment, and is inflated and deployed at the time of a collision in which a force that causes the occupant to move obliquely forward acts Good. According to this configuration, it is possible to restrain the occupant from moving diagonally forward at the time of a collision in which a force that moves the occupant diagonally forward acts. In particular, since the airbag device is deployed obliquely in front of the outside of the seat, the space between the airbag attached to the front portion of the vehicle and the curtain airbag attached to the side portion of the vehicle is cushioned at the time of a collision. It is possible to fill. Thus, in the event of a collision in which a force that moves the occupant diagonally forward acts, the airbag that the occupant is attached to the front of the vehicle is restrained and the curtain that is attached to the side of the vehicle is restrained. It is possible to prevent slipping through the space between the airbag.

  Further, since the airbag device of the present invention is provided on the floor of the passenger compartment or embedded in the floor, for example, not only the front side of the driver seat and the front passenger seat but also the front side of the rear seat. Can also be provided. As a result, it is possible to prevent the occupant of the rear seat from moving obliquely forward on the outside of the vehicle, and for example, it can be prevented from hitting the shoulder of the driver seat or the passenger seat.

  The cushion of the airbag device may have a height that reaches a height equal to the head of the occupant seated on the seat. According to this configuration, it is possible to more sufficiently restrain the occupant from moving obliquely forward at the time of a collision in which a force that moves the occupant obliquely forward acts. Further, the space between the airbag attached to the front portion of the vehicle and the curtain airbag attached to the side portion of the vehicle can be sufficiently filled with a cushion at the time of a collision. Thereby, safety can be further improved.

  According to the present invention, it is possible to protect the occupant by restraining the occupant from moving diagonally forward and moving to the far side during a collision.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

(First embodiment)
FIG. 1 is a diagram exemplifying a vehicle compartment 100 in which far-side airbag devices 102 and 103 that are the first embodiment of the airbag device according to the present invention are implemented. In FIG. 1, the vehicle is, for example, an SUV (Sport Utility Vehicle). In the vehicle compartment 100, two in the vehicle width direction and two in the vehicle front-rear direction, a total of four seats, that is, the driver's seat 106, the passenger seat 108, the first rear seat 110, and the first seat Two rear seats 112 are arranged. There is no center console between the driver's seat 106 and the passenger's seat 108, but instead a walking path 114 is provided. In addition, a walkable path 115 is provided between the first rear seat 110 and the second rear seat 112. The passages 114 and 115 constitute the floor of the passenger compartment 100. In the vehicle illustrated in FIG. 1, the floor surface in the passenger compartment 100 is generally flat. In the following, arrows U, F, and R shown in the drawings respectively indicate the upper side of the vehicle, the front side of the vehicle, and the right side of the vehicle.

  As illustrated by a broken line in FIG. 1, a far-side air is provided in a passage 114 between the driver's seat 106 and the passenger seat 108 and a passage 115 between the first rear seat 110 and the second rear seat 112, respectively. Bag devices 102 and 103 are embedded under the floor. Therefore, most or all of the cushion 120 of the far-side airbag device 102 illustrated as a representative example of FIG. 2 is embedded under the floor.

  Although not shown, the far side airbag devices 102 and 103 may be provided so that at least a part thereof projects on the floor of the passenger compartment 100.

  Since the far-side airbag devices 102 and 103 have the same configuration and operation, the configuration and operation of the far-side airbag device 102 will be described as a representative. FIG. 2 is a view illustrating a state where the far-side airbag device 102 of FIG. 1 is inflated and deployed. FIG. 2 illustrates a state in which the driver seat 106 and the passenger seat 108 illustrated in FIG. 1 are viewed from the front of the vehicle.

  As illustrated in FIG. 2, the far-side airbag device 102 according to the first embodiment of the present invention includes one cushion 120 that inflates and deploys upward from the embedded passage 114 in an emergency. The cushion 120 is partitioned into a plurality of expansion chambers (chambers) in consideration of the position where the occupant can come into contact. In the present embodiment, the cushion 120 is partitioned into a first chamber 122 and a second chamber 124.

(First chamber)
As illustrated in FIG. 2, the first chamber 122 reaches the height H1 (FIG. 2) when expanded and deployed. The height H1 is a height corresponding to 1/3 of the vertical dimension L1 of the seat back 130 measured from the seating surface (upper end) of the seat cushion 128 of the passenger seat 108. Generally, when an occupant sits on a seat such as the passenger seat 108, the occupant's waist (pelvis) is in a range E from the seating surface of the seat cushion 128 to a height H1. Therefore, the first chamber 122 reaches a height equal to at least the waist 160 of the occupant 156 that has moved to the far side at the time of a side collision, and can reliably restrain the waist 160. As illustrated in FIG. 2, in the present embodiment, the first chamber 122 has a rectangular parallelepiped substantially similar to the center console when inflated and deployed. As illustrated in FIG. 2, the first chamber 122 has a vertical dimension L2, a width W1, and a depth (not shown).

  The width W1 (length in the vehicle width direction) of the first chamber 122 at the time of expansion and deployment in FIG. 2 is equal to or less than the distance D1 between two seats arranged side by side in the vehicle width direction. Preferably, the width W1 is substantially equal to the distance D1. Thus, at the time of inflating and deploying, the side surface 132 on the side of the passage 114 of the seat cushion 128 of the passenger seat 108 that is one seat and the side surface 136 on the side of the passage 114 of the seat cushion 134 of the driver seat 106 that is the other seat are: Each abuts against the first chamber 122. That is, since the first chamber 122 is inflated and deployed so as to be sandwiched between the seat cushions 128 and 134 of two seats, the first chamber 122 can be stably inflated and deployed.

  FIG. 3 is a diagram illustrating a situation where an occupant is restrained by the far-side airbag device 102 of FIG. FIG. 3 illustrates a situation where the occupant 156 seated on the passenger seat 108 is restrained by the cushion 120. As described above, since the first chamber 122 has a rectangular parallelepiped shape substantially similar to that of the center console, the passage 114 where the center console does not exist can be filled by the first chamber 122 at the time of collision. As illustrated in FIG. 3, the waist 160 of the occupant 156 is restrained by the first chamber 122, and prevents the occupant 156 from hitting an occupant in the adjacent seat or an interior part (such as an adjacent seat).

  Although not shown, the depth of the first chamber 122 (the length in the vehicle longitudinal direction) is substantially the same as the depth of the seat cushions 128 and 134 (the length from the front end to the rear end of the seat cushions 128 and 134). It is preferable. By doing so, it is possible to restrain the waist 160 of the occupant 156 regardless of whether the occupant 156 is seated deep in the seat or seated shallowly.

  More preferably, the depth of the first chamber extends to the rear of the vehicle so that the first chamber 122 faces the side surfaces 140 and 142 of the seat backs 130 and 138 of both seats. In this manner, as illustrated in FIG. 3, even when an occupant 156 seated on one seat leans against the cushion 120 at the time of a collision, the first chamber 122 is formed on the side surface 142 of the seat back 138 of the other seat. It comes to be supported. Therefore, the movement amount of the first chamber 122 to the side opposite to the leaning side can be suppressed, and the waist 160 of the occupant 156 can be stably restrained.

(Second chamber)
As illustrated in FIG. 2, the second chamber 124 is a portion formed above the first chamber 122. When the second chamber 124 is inflated and deployed, the second chamber 124 reaches a height at least equal to the headrests 150 and 152 of the seat (the portion on which the head 162 of the occupant 156 in FIG. 3 leans). As illustrated in FIG. 2, in this embodiment, the second chamber 124 is a rectangular parallelepiped as well as the first chamber 122, and the vertical dimension L <b> 3 is about 2.5 times the vertical dimension L <b> 2 of the first chamber 122. . The second chamber 124 has the same width W1 and depth (not shown) as the first chamber 122. Therefore, as illustrated in FIG. 3, the second chamber 124 is inflated and deployed so as to be sandwiched between the side surfaces 140 and 142 of the seatbacks 130 and 138, thereby enabling stable restraint of the occupant's head.

  The shapes and dimensions of the first chamber 122 and the second chamber 124 are not limited to those shown in FIG. 2, and any shapes and dimensions may be adopted as long as the occupant's waist and head can be restrained in the event of a collision. Good.

  Each part of the cushion 120 (the first chamber 122, the second chamber 124, etc.) is formed by a so-called cut and sewn, in which two fabrics (base fabrics) on the front and back are overlapped and sewn, bonded, or both. Alternatively, it can be formed into a bag shape (a bag shape when a duct exists) by an OPW (One-Piece Woven) method.

(Second Embodiment)
FIG. 4 is a diagram illustrating a state in which the far-side airbag device 202 according to the second embodiment of the airbag device according to the present invention is inflated and deployed. The far side airbag device 202 according to the second embodiment can be implemented in place of the far side airbag device 102 in FIG. 4, the same elements as those of the first embodiment shown in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.

  As illustrated in FIG. 4, the far-side airbag device 202 includes two cushions, that is, a first cushion 204 disposed on the passenger seat 108 side and a second cushion 206 disposed on the driver seat 106 side, Thus, a space between the driver's seat 106 and the passenger seat 108 is filled.

  As illustrated in FIG. 4, the first cushion 204 includes a first chamber 212 and a second chamber 214 similar to the cushion 120 of FIG. 2. The first chamber 212 is a rectangular parallelepiped having substantially the same shape as that obtained by dividing the center console in half along the vehicle front-rear direction when inflated and deployed, and has a vertical dimension L2 equal to the first chamber 122 of FIG. It has a length (not shown) in the longitudinal direction of the vehicle. Therefore, the first chamber 212 is a portion that reaches at least a height equal to the waist of the occupant 210 seated in the passenger seat 108 and restrains at least the lumbar of the occupant 210. The width W4 of the first chamber 212 at the time of expansion and deployment is substantially ½ of the distance D1 between two sheets arranged side by side in the vehicle width direction.

  The second chamber 214 is also substantially a rectangular parallelepiped when inflated and deployed, and has a vertical dimension L3 and a length in the vehicle front-rear direction (not shown) equal to the second chamber 124 of FIG. Therefore, the first cushion has a height that reaches the same height as the head of the occupant 210 seated in the passenger seat 108, and the second chamber 214 restrains the head of the occupant 210 seated in the passenger seat 108. doing. The second chamber 214 also has a width W4 that is substantially ½ of the distance D1 when inflated and deployed.

  The second cushion 206 is not divided into a plurality of chambers and is a rectangular parallelepiped having substantially the same shape as the first chamber 212. The vertical dimension L2, the width W4, and the length in the vehicle front-rear direction are the same as those of the first chamber 212. (Not shown). Therefore, the second cushion 206 reaches at least a height equal to at least the waist of the occupant 220 seated on the driver's seat 106 when inflated and deployed, and restrains at least the lumbar of the occupant 220.

  In the present embodiment, the first chamber 212 and the second chamber 214 have a width W4 that is substantially ½ of the distance D1 when inflated and deployed. However, the present invention is not limited to this, and the seat together with the second cushion 206 As long as the space between them can be filled, you may increase or decrease freely. In particular, in the present embodiment, since the second cushion 206 is not divided into a plurality of chambers, the width W4 of the second chamber 214 may be freely increased or decreased.

  Thus, in the far side airbag device 202 according to the second embodiment, the space between the two seats arranged in the vehicle width direction is filled with the two cushions (the first cushion 204 and the second cushion 206). . Therefore, for example, when the occupant 210 of the passenger seat 108 in FIG. 4 leans against the first cushion 204 due to a side collision from the far side (left side in FIG. 4), the first cushion 204 causes the opposite side 224 of the second cushion 206 to be opposed to the first cushion 204. Is supported by the side 226. Therefore, the movement amount of the first cushion 204 is suppressed as compared with the case where there is only one cushion 120 in FIG. 2, and the occupant is prevented from falling too far into the far side.

  In the present embodiment, the first cushion 204 has two chambers, a first chamber 212 and a second chamber 214, so that the head of the occupant 210 can be restrained, but the second cushion 206 has the same configuration. The head of the occupant 220 may be restrained. Alternatively, the first cushion 204 may be configured only by the first chamber 212 and may be configured to restrain only the waists of the occupants 210 and 220.

(Third embodiment)
FIG. 5 is a view taken in the direction of arrow A in FIG. In FIG. 5, the passenger seat 108 and the second rear seat 112 in FIG. 1 are viewed obliquely from the front. An airbag apparatus 302, 304 according to a third embodiment of the airbag apparatus according to the present invention will be described with reference to FIG. In the following drawings, the same elements as those shown in FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof is omitted.

  As indicated by the dotted lines in FIG. 5, airbag devices 302 and 304 are respectively located under the floor on the diagonally forward side of the vehicle exterior (door side) of the seat cushion 128 of the passenger seat 108 and the seat cushion 129 of the second rear seat 112. It is buried in. Therefore, most or all of the cushion 320 of the airbag apparatus 302 illustrated as a representative example in FIG. 6 is embedded under the floor. Although not shown, the airbag devices 302 and 304 may be provided so that at least a part thereof protrudes on the floor of the passenger compartment 100.

  Since the airbag apparatuses 302 and 304 have the same configuration and operation, the configuration and operation of the airbag apparatus 302 will be described below as a representative. FIG. 6 is a view illustrating a state where the airbag device 302 of FIG. 5 is inflated and deployed. FIG. 6 illustrates a state in which the passenger seat 108 of FIG. 5 is viewed from the outside of the vehicle.

  As illustrated in FIG. 6, the airbag device 302 according to the third embodiment of the present invention is inflated and deployed at the time of a collision in which a force that moves the occupant 156 obliquely forward acts on the vehicle. Examples of such a collision include a case where an oblique front of the vehicle receives an impact. In the present embodiment, as illustrated in FIG. 6, the airbag device 302 includes one cushion 320, and the cushion 320 is removed from the floor at the time of a collision in which a force that moves the occupant 156 obliquely forward acts on the vehicle. It expands and expands diagonally upward. As illustrated in FIG. 6, the cushion 320 has an oval shape and is not partitioned into a chamber. However, the present invention is not limited to this, and may be partitioned into a plurality of chambers, such as the cushion 120 of the far side airbag device 112 according to the first embodiment.

  In the present embodiment illustrated in FIG. 6, the airbag device 302 is inflated and deployed on the diagonally forward side of the seat cushion 128 on the vehicle outer side (door side). Thereby, it is possible to restrain the movement of the occupant 156 obliquely forward at the time of a collision in which the force of the occupant 156 moving obliquely forward acts. In particular, when the airbag device 310 attached to the front portion of the vehicle such as the dashboard 308 and the curtain airbag device 312 attached to the side portion of the vehicle such as the side rail are inflated and deployed, the space between the respective cushions is increased. It is possible to fill with a cushion 320 at the time of collision. Thereby, it is possible to prevent the occupant 156 from slipping through the space between the airbag device 310 in the front portion of the vehicle and the curtain airbag device 312 in the vehicle side portion.

  Further, as illustrated in FIG. 5, an occupant (not shown) seated in the second rear seat 112 can be attached to the outer side of the vehicle by embedding the airbag device 304 obliquely in front of the second rear seat 112 on the vehicle outer side. It is possible to suppress the movement to the front diagonally. As a result, it is possible to prevent an occupant of the second rear seat 112 from hitting the shoulder of the passenger seat 108, for example. Although not shown, such an airbag device can be provided diagonally in front of the driver's seat 106 and the first rear seat 110 (FIG. 1) on the outside of the vehicle.

  In FIG. 6, the cushion 320 has a height that reaches a height equal to the head 162 of the occupant 156 seated on the passenger seat 108 when inflated and deployed. Specifically, the cushion 320 has a vertical dimension L4 so as to reach a height at least equal to the headrest 150 of the seat 108 when inflated and deployed. In this way, the cushion 320 has a height that reaches a height equal to the head 162 of the occupant 156, so that the occupant 156 can move more obliquely forward at the time of a collision in which a force that causes the occupant 156 to move obliquely forward acts. It can be restrained sufficiently. Further, the space between the airbag device 310 at the front of the vehicle and the curtain airbag device 312 at the vehicle side can be sufficiently filled with the cushion 320 at the time of a collision. The cushion 320 may reach a height equal to at least the waist 160 of the occupant 156 seated on the passenger seat 108 when inflated and deployed.
